FAPORIZING ATTACHMENT FOR INTERNAL-COMBUSTION ENGINES.

. Application tiled July 7, 1916, Serial No. 108,018. Renewed September 12, 1918.

To all whom it may concern.'

Be it known that I THOMAS PEPLER, a citizen ofthe United States, residing at Iowa City, in the county of Johnson and State of Iowa, `have invented new and useful vlinpovements in Vaporizing Attachments for Internal-CombustionEngines, of which the following is a specification.

This invention relates to appliances for internal combustion engines and more particularly to that type of such devices which have as their object to economize in the co-nsumption of fuel.

It is one aim of the present invention to provide a device of the class above mentioned so constructed that in the operation thereof heated air will be admitted to the intake manifold for the purpose of more thoroughly vaporizing the gasolene or other` fuel.

The invention has as a further object the rovision of a device of the class mentioned includin a valve which will be entirely automatic 1n its action for the purpose of controlling the admission of heated air to the intake manifold, and a pipe coil which is connected with the said valve and which is so assembled with the exhaust manifold -as to provide for economical heating of the air which is to pass through the said valve.

In the accompanyii drawings,

Figure 1 is a side e evation of the device embodying the present invention in use.

Fig. 2 is a vertical sectional view through the valve of the device.

In the drawings, the numeral 5 indicates the engine in connection with which the device is to be employed, 6 being the intake manifold, and 7 the exhaust manifold. The device includes, as before stated, a valve for automatically controlling the admission of heated air to the intake manifold and a pipe coil which is assembled with the exhaust manifold for the purpose of heating the lair, and in the drawings the numeral 8 indicates the said pipe which surrounds the exhaust manifold 7 and which has an intake end 9 and an extension 10 which leads to and communicates with the valve above mentioned.

The valve includes in its structure a casing which is indicated in general by the numeral 11, and which is interio-rly reduced at its upper end to provide an inlet port 12 communicating at its lower end with a valve seat 13. The upper end of the casing is ex- Specication of Letters Patent.

teriorly threaded and has fitted thereto a cap 14 securing in place the fianged end 15 of the extension 10 of the pipe coil, the said extension communicating with the port 12 as clearly shown in Fig. 2 ofthe drawings. The casing of the valve is interiorly threaded at its lower end to receive the upper threaded end of a plugl, the lower end of which plug is fitted into the wall of the intake manifold 6 as shown in Fig. 1. The numeral 17 indicates the head of the valve which normally rests against the seat 13 and which is held in such position by means of a. spring 18 which is fitted around the stem of the valve and which bears at its upper end against the under side of the valve head 17, and at its lower end aga-inst the upper end of the plug 16. The stein of the valve is indicated byl the numeral 19, and the said stem is tubular and is pro-vided directly beneath the head of the valve with side inlet ports 20 of which there may be any desired number. The lower end of the stem fits slidably through a bore 21 formed axially within the plug 16 and the lower end of the said stem is closed as indicated by the numeral 22. Immediately above its closed lower end, the stem is formed with side outletports 23 of which there may be any suitable number.

As above stated, he valve headl'? is normally held to the seat 13 by the spring 18. However, when suction is created within the intake manifold the valve will open to admit heated air from the coil 8 through the port 12, and the inlet ports 20 of the valve stem, the air passing through the valve stem andthe outlet ports 23 into the said intake manifold where it acts to more completely vaporize the asolene prior to admission to the engine cy inders. It will be understood of course that the volume of heated air admitted at each opening of the valve will be governed by the extent to which the outlet ports 23 are uncovered below the lower end `of the plug 16. l

I claim: l. In an appliance of the class described,

a casing havlng an air inlet, a valve seat within thel casing, and a valve including a head normally held against the said' seat, and a stem slidably fitted through the casing and projecting therefrom, the said stem being hollow and being provided adjacent to the valve head with an inlet'port and at its portion which projects from the casing With an outlet port, the end of the casing from which the stem projeets having means `for attachment to' the part to which the valve' delivers.

2. In an appliance of thc class described, a casing havingan air inlet7 la valve seat Within the casing, the casing having a port establishing communica-tion between the air inlet and the valve seat, a valve havin a head tting the said seat, means yieldaly holding the head of the valve to its seat, and a hollow stem for the valve extending from the head through the casing and projecting tl'ierefroin, said stein being provided adjacent to the head With an inlet port and at its portion which projects from the casing, with an outlet port, the end of the casing from which the stem projects having means forattachment to -thepart to which ftliejvalve delivers.

3'. In a device of the class describech a casing having an' air inlet, the v'easing beingv provided intcriorly with a valve seat and with a bore, and a valve arranged Within the casing and having a headnormally engaging tie seat and provided with a tubular stem fitting slidably through the. bore and projecting therefrom, the said steinibeing E' provided adjacent the head of the valve with an inlet por-t, and being also provided With an outlet port the effective area of rwhich varies with the movement of the stemwith relation to the end of the `said lbore, the lend of the casing from Which the .stein projects having means for attachment to the part to which the valve delivers. v

In testimony whereof-I affix my signature.
